Question

Got prompted for an update and let it do its thing and got these errors everything worked fine before the update.

Information:Gradle tasks [:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:compileDebugAndroidTestSources, :app:compileDebugUnitTestSources, :app:compileDebugSources]

I've come across several similar questions, but none of the answers worked for me. I've cleaned and rebuild the project and I updated all the dependencies in Gradle. EDIT: Gradle syncs fine, but the project build gives error

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId "com.anatomie.bny.topografie"
        minSdkVersion 17
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile files('libs/android-support-v13.jar')
    compile files('libs/picasso-2.5.2.jar')
    compile 'com.android.support:support-v4:26.1.0'
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:support-vector-drawable:26.1.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:design:26.1.0'
    compile 'com.squareup.okhttp:okhttp:2.4.0'
    compile 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'
    compile 'com.github.AndroidDeveloperLB:AutoFitTextView:4'
    testCompile 'junit:junit:4.12'
}

Please help, I've been at it for hours and can't find a solution

Answer 1

Change the plugin version in your project-level build.gradle file as follows:

buildscript {

repositories {
    ...
    // You need to add the following repository to download the
    // new plugin.
    google()
}

dependencies {

    classpath 'com.android.tools.build:gradle:3.0.0'
}

}

then Rebuild project

Answer 2

You can try my answer. And also restart Android Studio after following these steps.

Answer 3

Delete .gradle and .idea folder

And REBUILD

If that doesn't work, again delete .gradle and .idea folder

and RESTART
